发明名称 Techniques for sharing data
摘要 Techniques for sharing data between users in a manner that maintains anonymity of the users. Tokens are generated and provided to users for sharing data. A token comprises information encoding an identifier and an encryption key. A user may use a token to upload data that is to be shared. The data to be shared is encrypted using the encryption key associated with the token and the encrypted data is stored such that it can be accessed using the identifier associated with the token. A user may then use a token to access the shared data. The identifier associated with the token being used to access the shared data is used to access the data and the encryption key associated with the token is used to decrypt the data. Data is shared anonymously without revealing the identity of the users using the tokens.

主权项 1. A method of sharing data, the method comprising: generating a first physical token and a second physical token, each of the first and the second physical tokens comprising an identifier and an encryption key, wherein the identifier is associated with a location for storing encrypted data, after generating the first and the second physical tokens, receiving, by one of one or more computer systems, information identifying data to be shared; receiving, by the one of the one or more computer systems, information read from the first physical token, the information comprising the identifier and the encryption key; encrypting, by the one of the one or more computer systems, the data to be shared using the encryption key read from the first physical token to generate encrypted data; causing, by the one of the one or more computer systems, the encrypted data to be stored using the identifier; obtaining the identifier and encryption key from the second physical token; accessing the encrypted data using the identifier obtained from the second physical token; decrypting the encrypted data using the encryption key obtained from the second physical token to produce decrypted data; and enabling access to the decrypted data.
